The figure shows a shape that is made up of a rectangle and a half circle.
To find the total area of that composite figure, you find the area of the rectangle and the area of the half circle, and you add them together to get the total area.
Rectangle:
[tex] A = LW [/tex]
Circle:
[tex] A = \pi r^2 [/tex]
Total area = area of rectangle + area of half circle
[tex] A = LW + \dfrac{1}{2}\pi r^2 [/tex]
[tex] A = 16~m \times 12~m + \dfrac{1}{2} \times 3.14 \times (5~m)^2 [/tex]
[tex] A = 192~m^2 + 39.25~m^2 [/tex]
[tex] A = 231.25 ~m^2 [/tex]
